وَعَنْ عَائِشَةَ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يُصَلِّي جَالِسًا فَيَقْرَأُ وَهُوَ جَالِسٌ فَإِذَا بَقِيَ مِنْ قِرَاءَتِهِ قَدْرُ مَا يَكُونُ ثَلَاثِينَ أَوْ أَرْبَعِينَ آيَةً قَامَ وَقَرَأَ وَهُوَ قَائِمٌ ثُمَّ رَكَعَ ثُمَّ سَجَدَ ثُمَّ يَفْعَلُ فِي الرَّكْعَةِ الثَّانِيَةِ مِثْلَ ذَلِكَ. رَوَاهُ مُسلم

Aisha reported that the Messenger of God used to pray seated, reciting while seated. When about thirty or forty verses remained of his recitation, he would stand and finish reciting while standing. Then he would bow and prostrate, and he did the same in the second unit. Muslim transmitted it.
